IMPROVEIJ WINDOW-BLIND.

The Schedule referred to in these Lette-rs Patent and making part of the same To all whomt may concern Beit known that we, ANTHONY Prnz and MANUEL PIRZ, of 'East New York, in the county'of- Kings, -n the State of New York, have invented certain new and usefullmprovements in 'WindowfBlinds and Shutters and we do hereby declare that the following is a full and exact description thereof.

Ourinvention provides, in the same structure, the

ordinary blind, a sub-blind or small blind, which canbe opened with less trouble than the main blind, and swings horizont-ally like the main blind, and an adjustable awning, which swings up, and is secured' at various inclinations.

We will first describe what we vconsider thel best means of carrying out our invention, and will after- `Figure 3 is a section partly in elevation, showing.

what we .term the sub-b ind, as swung partly open by turning on its vertical hinges. I A

Figure 5 is an edge view, representing the part which we term the sub-sub-blind or awning, as swung partly open by turning 'on its horizontal hinges.

Similar letters of reference indicate like parts in all vthe figures.

A A, 85o., is the ordinary substantial work or frame of a blind. It is divided into two sections, an upper and a lower, by the cross-bar near the middle height.

The upper section is made in the form of 'an ordinary venetian blind or rolling-Slat blind, as it is sometimes called.

The lower section is also correspondingly provided with rolling-slats, but is compound and peculiar in its constiction.

Immediately within the main frame A,`1n thelower section, is a smaller' frame, B, hinged to the main frame Aby biithinges, b b, at ,the sides. On these hinges the frame B and its contents can be swung outward to any desired extent. l y i When vclosed, it is secured by a double button or analogous device, b

Immediately within the frame B is a frame C, hung vto the frame B at its upper edge by two but-hinges, c c.

In this ame C the rolling-slats D are mounted in any approved manner, and may serve their ordinary `function without using the peculiar advantages of my frames C and B. In otherwords, my blind may serve in all ordinary respects like other blinds, and the op-v In such case, it willbe about as good as the ordinary blind, the fragnin'g around the lower section being simply a little widerand more compound in its structure. yWhen itis desired 'to enjoy the advantages of my invention, the lower section may be opened in two ways, either together or separately, without disturbing the general frame A of the blind. It will rarely be desirable, in practice, to open the lower section both ways at once, but it will ordinarily be used in one or the other of the two following plans: v

First, turn the button b and liberate the i'ame B from its rigid connection with the frame A, and turn the frame B andits entire contents 'around -on the hinges b. The subblind, composed of the frame B and its; contents, may thus be swung open and held by any approved means at any desired position ;A or,

Second, supposing the frame B again rigidly connected to the frame A by the button b', turn the button o', which otherwise would hold the frame (l rigidly connected tothe frame B. AThis liberates the frame C andallows it to be swung out at the bottom, turning 'upon the hinges c o at the top. v In other words,

the frame '0, with its contents, turns in the vertical plane and assumes an angular' position, somewhat like an awning projecting from a window.

- In this latter mode of operating, I esteem it absolut ly essential to success that the frame (l and its co tents beheld at various adjustable positions; that y is to say, that'it be heldin a position nearly horizontal, or in a position nearly vertical, or at various oblique angles between.

I hold it in these positions 'by means of the pawl D', which turns upon the pivot d, ixed in the frame B.

The frame B is recessed to allow 'for the thickness of the pawl D', and theA adjacentginner edge of the frame C is notched, as represented by E E. These notches receive the end of the pawl D.

If the frame C and its connections are swung out but a little ways, the first notch receives the end of the pawl; if it is swung out a little inther,`the second notch receives and holds the end, Sto.

Having once mounted the fraine in position, it will remain so for-an indefinite period, always excepting the possible contingencyoi' a violent gale or tornado. In ordinary weather the frame will remain suspended by'this means, at the angle desired, until the approach of night or other cause makes it desirable to close the blind, when, by raising the inclined frame C by the hand, the pawl is liberated and may be drawn down into its perpendicular position, and the frame O closed into the corresponding position, and secured again, as before. \Ve propose, in some cases, to apply mosquito-netting over the whole inner face of the blind; and in such cases, the main blind A requires to be opened a little ways to allow the sub-frame B or C to be operated.

Holding the lower section open by either of the modes suggested, but preferably by the last, so as to letY the frame O and its contents serve as am awning, we are able to receive the air through the mosquitonet, and, at the same time, to graduate the light and shade, and to avoid straining the mosquito-net or rubbing it, as would occur in operating the ordinary rolling-slats.

W e can apply our. invention to blinds without rolling-slats, or to wood or iron shutters, or structures of various other kinds. It can be used with good effect in any blinds, shutters, or the like, where it is required to open the lower part and not to open the entire blind, or where it is desired to shade the lower part of the Window in the manner of an awning, and allow unobstructed view, conversation, &c., below. We do not claim swinging an entire shutter or blind out at various angles, so as to form an awning of such entire shutter; but, having now fully described our construction, r

1. The internal shutter or panel O, mounted within the'main shutter A, and adapted to swing `outward therefrom, as specified.

` 2, 'lhe triple flames or parts A, B, and O, when ter, the part B forms a suh-frame, swinging on a verinternal shutter or panel for the second frame B, all the parts being combined and airan ged for joint operaf tion, as and for the purposes herein set forth.

In testimony whereof, we have hereunto set our names, in presence of two subscribing witnesses.
